Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] Such as figure 1 Shown is the overall structure block diagram of the present invention. The device of the present invention is applied to a traditional servo drive to support field bus communication and realize the function of field bus control. The hardware part of the device of the present invention includes: a field bus peripheral interface circuit, an FPGA logic chip, a serial bus communication circuit, an FPGA reset circuit, and a stack number setting circuit.

[0035] The serial bus communication circuit transmits the control information and data from the host computer of the FPGA to the servo drive in the form of serial bus signals, and transmits the status information, error alarm information and equipment information of the servo drive to the FPGA.

[0036] Such as figure 2 Shown is the FPGA logic block diagram of the presen...

Abstract

The invention relates to servo server control in the field of industrial automation, in particular to a control system and method of a servo driver field bus interface. The control system comprises a field bus peripheral interface circuit, an FPGA module and a serial bus communication circuit module. The control method comprises an uplink process control method and a downlink process control method. The control system and method enables a traditional servo server to be capable of being connected to a field bus and mixed with other field bus devices in use, the control system and method adopts field bus communication and has the advantages of being good in anti-interference capacity, good in expansibility and the like, so that a distance between the system and the servo server can be several hundred meters, and the control system and method is suitable for a large machine tool. In addition, the number of connecting wires for a hanger and a power distribution cabinet is greatly decreased, and the electric appliance cabinet wire arrangement efficiency is improved.
